New words can be built freely in Pandunia! Pandunia has a word derivation system that is regular and productive.
How to combine words?
Pandunia words are made up of roots and suffixes. A root is that part of word that refers to something in the world outside the language. A suffix is a vowel ending that has mainly a grammatical function. For example, the word zemia 'planet Earth' consists of the root zem- 'earth, soil' and the collective noun suffix -ia.
zem- 'earth, soil' + -ia 'a noun ending' _____________ = zemia 'planet Earth'
Two or more roots can be put together to make compound words. The last root is the most meaningful part in the compound and the preceding roots only modify its meaning.
pan- 'all' + dem- 'people, public' + -i 'adjective ending' _____________ = pandemi 'pandemic'
Joining roots together could sometimes result into unpronounceable consonant sequences. For example, the consonant sequence -tgr- could appear when the roots fot- and graf- were put together. Then the connecting vowel -o- is inserted between the roots to make pronunciation easier.
fot- 'light' + -o- 'connecting vowel' + graf- 'picture, image' _____________ = fotograf 'photograph'
There are two more examples below.
dem- 'people, public' + -o- 'connecting vowel' + krat- 'rule, govern' + -ia 'a noun ending' _____________ = demokratia 'democracy' term- 'temperature' + -o- 'connecting vowel' + met- 'measuring' + or- 'apparatus' ____________ = termometor 'thermometer'
Some roots are used frequently as prefixes but seldom as words on their own. These international prefixes include the roots a-, de-, pro-, re- and su- among others. Pandunia has adopted them in order to re-create many international words as native Pandunia words.
a- 'to, toward' + ces- 'pass' ____________ = acese 'get past to, access' pro- 'forward, to the front' + ces- 'pass' ____________ = procese 'pass forward, process' re- 'back to' + ces- 'pass' ____________ = recese 'pass back, recede' de- 'away, off' + ces- 'pass' ____________ = decese 'pass away, die' su- 'good, well' + ces- 'pass' ____________ = sucese 'go well, succeed'
Note that these prefixes are used only in compound words that really mean the sum their parts. Fossilized words whose meanings are no longer the sum of their parts, like evolution (originally 'rolling out') and revolution (originally 'rolling back'), are not compound words in Pandunia.
Compound words – together or separately?
It doesn't matter are the elements of a compound word written together or separately – both ways work without problems. So, for example, the word for 'mailbox' can be written poste kase or postokase and the word for 'democracy' can be written deme kratia or demokratia.
Prefixes and suffixes are very important and give great flexibility to the language. The most useful ones are listed here. Most of them are in fact ordinary words that are also used on their own, but some are true prefixes or suffixes and can be used only as such, not as separate words.
